dc-location-to-buffer-location

Converts the given coordinates from top-level view coordinates (usually canvas coordinates) to buffer location coordinates. The same calculation is performed by global-to-local.

The result is only valid when the buffer is viewed (see Basic Organization).

• (send a-wx:media-buffer dc-location-to-buffer-location x y) -> two inexact reals
      x : inexact real
      y : inexact real

  Returns the equivalent of x and y translated from DC coordinates to buffer drawing coordinates.
